Ben's opinions on Personal-Assistants.

tl;dr They're not personal assistants.

Siri, Google Assistant, Cortana, Alexa, etc.. The generic term is "personal assistants," but that's just a metaphor, like
"virtual reality". In my opinion, a personal assistant, human or otherwise, must be able to do hear and form a
respone to the following in a reasonable amount of time:

"Where did I save that podcast I started listening to yesterday?"

"Who was I going to call?"

"Call them and ask for a refund."

"Send Chris this photo via Hangouts."

"Turn on my desktop and send me the Excel version of this Google Sheet that I'd saved on it."
